• little doubt about serialization?

  Hello
  I'm serialization of an object that implements serializable using ObjectOutputStream but this object class is not a constructor argument. When it is deserialized object is being built back again. But how is that possible? "Class.forName" also requires the class object has no constructor args. so in the deserialization how the object is built back again even if she has no constructor args? I'm trying to understand how this is possible? can someone help me understand the logic?

  If it is not compatible with JDK serialization, it is a bug in Android.

• Little doubt about VMware Fault Tolerance

  I would like to know, in case if the Virtual Machine goes down or get corrupted, the setting of Virtual Machine replica on the secondary host is going live?

  Else FT is applicable only when the broken material / host, please provide details?

  Both machines use the same storage and the second machine is basically running the same instructions as the first. If the first has been tampered on disk or a memory error, it appears in the second. FT is realtime protection against hardware failures.

• Doubts about event handlers

  Hello
  
  I had some doubts about the event handlers in the IOM 11.1.1.5...
  
  (1) I want to use the same event handler for the message insert and update Post task... Can I use the same handler for this... If Yes, then how can I make...
  
  (2) can I create the single class of Plugin.xml and add all the jar files in IE single lib folder and zip them all together... If yes then what changes I need to do? Need only add that the plugin tags for different class in the plugin.xml file files? OR need to do something extra too...?
  
  (3) if I need to change something in any class handler... Is it need to unregister the plugin and register again...?
  If Yes... Is it need to delete the event handler using the weblogicDeleteMetadata command?
  
  (4) that we import the event handler of the path as event manager/db /... If we add all the evetn handler.xml files in this folder... As when importing weblogicImportMetadata called recursively all files in this folder... Now, if I need to change anything in one of the event handler class... so if import us from the same event manager/db folder... What to do... Create the copy of the eventhandlers? OR should I not add Eventhandler.xml files to class files, I made the changes...
  
  (5) given that I need to create emails on the creation of the user while recon and identification of email updated as a first name or surname updates... I had to use in the event handler.xml (entity-type = 'User' operation = "CRΘER") or something else...
  
  
  Help me clarify my doubts...

  Yes, on the update post you need to be check first if the first and last name change to update the mail electronic id, rather then calculation always email identification. So, you can check the path name are updated through the previous code.

• Doubts about licenses

  Hi all
  
  I have a few doubts about the price of licenses.
  
  I understand, I can deploy an APEX Server 11g XE free of charge, but what happens, if I want to install, a version no XE?
  
  Imagine a billing application, for 10 users, and I will assume that a Standard is sufficient. With the help of [this price list | http://www.oracle.com/us/corporate/pricing/technology-price-list-070617.pdf], how much exactly will cost?
  
  I understand I can get a license by user or server, or I have to license user and server too?
  
  Kind regards.

  Hello
  metric license is named plu user or license CPU (see the table of the core).

  for a quote, you can take a look in the oracle store or ask your dealer for an exact price oracle.

• I have a doubt about the file .folio and publications

  Hello, I m new here.

  I want to start working with DPS, but I have a doubt about which version to buy.

  At the moment I have one customer just wants to publish a magazine, but my intention is to have more customers and publish more magazines.

  If I buy the unique edition of DPS, I read that I can publish a single file .folio. What it means? Each folio file represents a publication?

  Please, I need help to understand this before you purchase the software.

  Thank you very much

• Doubt about appsutil.zip in R12

  Hi all
  I have doubts about the application of rapid Clone on 12.1.3.I the latest patches have applied the fix using adpatch. After that, it must synchronize directories appsutil
  in RDBMS oracle home. I created appsutil.zip in the application layer and copied in the RDBMS oracle home. If I move the old appsutil to appsutil.old and extract appsutil.zip, the new appsutil directory should not constituted by the context file (I think). So, I have to run the automatic configuration based on the old cotextfile. Below, I have summarized the steps that I follow. Please check and correct me if I'm wrong.
  
  Copy appsutil.zip to $INST_TOP/admin/out of RDBMS oracle home
  CP $CONTEXT_FILE /tmp/mytest_vis.xml
  MV appsutil appsutil.orig
  unzip appsutil.zip
  Run autoconfig based on/tmp/mytest_vis.xml.
  
  
  Thank you
  Jay

  Jay,

  Is there a reason why do not use the old file context? What is the difference between the context file that will be generated by adbldxml.pl and the old file context?

  If there are updates in the application, it will be updated in the new xml file generated by adbldxml.sh, but he's not in the old file.

  So it is always best to run adbldxml.sh and autoconfig.

• Doubts about RAC infrastructure with a disk array

  Hello everyone,
  
  I am writing because we have a doubt about the correct infrastructure to implement RAC.
  
  Please, let me first explain the current design we use for storage Oracle DB. Currently, we are conducting multiple instances in multiple servers, all connected to a SAN disk storage array. As we know that it is a single point of failure so we have redundant controlfiles, archiveds and Orde in the table and in the internal drive of each server, in which case table has completely failed us 'just' need to recover cold backup nightly, applied hoops and Oder and everything is ok. This is possible because we have autonomous bodies and we can assume that this downtime of 1 hour.
  
  Now, we want to use these servers and implementing this table to a RAC solution and we know that this table is our only point of failure and wonder if it is possible to have a RAC multi-user solution (not AS a node) with controlfiles/archs/oder redundant internal drives. Is it possible to have each written full node RAC controlfiles/archs/oder in drives internal and applies these files systematically when the ASM filesystem used for CARS is restorations (i.e. with a softlink in an internal drive and using a single node)? Maybe the recommended solution is to have a second table to avoid this single point of failure?
  
  Thank you very much!

  Fix. It is the right solution.

  In this case, you can also decide to simply use the distribution on both tables and mirror of the array1 array2 on table data using the ASM redundancy options.

  Keep in mind that the redundancy is also necessary for connectivity. If you need at least 2 switches to connect on two tables and two HBA ports on each server, 2 fibers running, one to each switch. You will need driver multichannel s/w on the server to deal with the multiple I/O paths for storing same lun.

  Similarly, you will need to repeat this step for your Interconnect. 2 private switches, 2 cards on each server which are pasted. Connect then these 2 network cards on the 2 switches, one NETWORK card per switch.

  Also, don't forget to spare parts. Spare switches (one for the storage and interconnection). Spare cables - fiber and everything that is used for the interconnection.

  Bottom line - not a cheap to have a redundancy solution. What we can do is to combine the layer of Protocol/connection of storage with the interconnection layer and run both on the same architecture. Oracle database machine and Exadata storage to servers. You can run your storage Protocol (e.g. PRSS) and your Protocol (TCP or RDS) interconnection on the same 40 GB Infiniband infrastructure.

  As well as 2 switches Infiniband are needed for redundancy, plus 1 spare. With each server running a dual port HCA and one cable for each of these 2 switches.

• Oracle import datapump fix corruption of block?

  Hi all
  I'm having a corruption of data on the production block. I want to export this DB and import it into a test using datapump environment, in order to do some tests on it.
  
  However, I'm concerned if impdp will solve this scenario... and that's why I'm going to lose my test scenario...
  It will be Oracle import datapump fix block corruption?
  
  Thank you

  Oracle does not have an import of block by block, including blocks corrupt so that the answer to your question is NO, corruption cannot be reproduced in this way.

• Reg: Objects & missing partitions while import datapump

  Hi Techies,
  
  I need urgent assistance on the case below I am facing currently.
  
  I imported a schema using DATAPUMP and it failed with the error "Failed to extend the tablespace" and for this dynamically when requested, I added a space.
  
  Its a grand scheme to export 120G dump file.
  
  The import log showed as completed successfully and when the AD team working on it they they found misssing some of the objects & partitions and it will be about 1000 + partitions.
  
  The one you suggest how to solve this problem without refreshing again...
  
  Thanks in advance...

  Say your team AD to set "a little." exactly which opposes and what partitions are missing. With this information, you can start new export only objects and the partitions that are missing, then import them and you will have the full data set, you don't have to import in the first test.

  The one you suggest how to solve this problem without refreshing again...

  There's no other way to do it logically correct. You could possibly play and have fun with links to the database and to add the missing items through some SQLs, but something as I have explained in a few lines above is certainly the more normal way to do it when you have scenario you described

• Parallel degree importing Datapump

  Hello

  For several imports that I ran, I observed a constant degree of parallelism = 10 when creating index.

  Moreover, I parallel_degree_limit = en parallel_degree_policy = MANUAL CPU.

  The first parameter specifies that Oracle sets up to an upper limit on the DOP.

  If this explains the value observed?

  Kind regards

  Hello

  At the same time goes like this:

  all the tables, plsql definitions are created in series

  All data in the table of loading in parallel - so not parallel insertion into a table but a work process separate datapump by table - so EMP would be charged by slave1 and DEPT by slave2 - but at the same time. IN your case 10 separate tables would all be imported at the same time.

  The indexes are built at the same time you specify

  Constraints are made in series one and the same process, I think

  I wrote a short blog about it earlier that can be useful: it contains pictures! :-)

• Question about importing video footage in Premiere Pro

  I'm new to Premiere Pro and have a question about it. I need to move all my videos on my new computer (Windows) from my old computer (iMac running iMovie). Where should I store my images so I can access inside Premiere Pro? I just need to store everything on a hard drive, and then create inside Premiere Pro projects when I need to import images in, or should I create a 'library' to store all my movies in? Setup bridge would be another beneficial way to view my videos (I use Lightroom for my photo library)? I'm just trying to discern the way I need to store and organize everything in order to get started with Premiere Pro. Thank you!

  Premiere Pro has no capability of database for the media in general, only in a specific project. 'Import' is not like in Lightroom, it does in PrPro is tell her where to look for the media while working on this specific project.

  So... you need create your materials on a particular disc, presented in a way that you can find them in a folder structure you design.

  A typical use of PrPro spreads parts on several disks. OS/programs on the system drive, a disk each cache PrPro & cache of database files; preview files; and project files. Media probably on another drive and exports on a final drive.

  Access the disk cache & cache database files, preview files and project files are the two ways of reading & writing, in addition to being constant. Multimedia files are used unalterable and exports only Scripture, their connections can be a little less robust.
